Listed here are some ideas for the NCD X-Term

NCD discoveries by Maki Kato — last modified 2004-11-04 22:58

working through the rom, I think I've found what looks like a printf.

NCD file CRC by Maki Kato — last modified 2004-12-02 01:02

the NCD 88k terminal loads a BCS file(COFF) with CRC at file offset 0xCC. With this, I'm one step closer to being able to cross compile for the NCD.

toolchain built but file format problems by Maki Kato — last modified 2004-11-12 15:56

binutils 2.15 built without much problems on a linux(fedora core 2) box using --target=m88k-ncd-none. For a test, I decided to use the one instruction "jmp r1" which for the 88k means return.

Starting to build the toolchain by Maki Kato — last modified 2004-11-08 23:40

I found the NCD term with the 2.7.3 rom and tried booting things that I compiled on the OpenBSD box and on the SysV/88k box and neither works.

File format and CRC by Maki Kato — last modified 2004-12-29 00:53

Further experiments seem to indicate that bits at file offset 0xC3 can signal whether to check for CRC or not.

Hello World runs on NCD 88k by Maki Kato — last modified 2004-12-31 01:06

Wrapping up the year with a milestone of printing a few words on the screen.

a little snapshot of the milestone.

hello.s by Maki Kato — last modified 2004-12-31 01:05

this is the hello world program. Making a call to the printf like routine(hardcoded) in the ROM. This probably only works with the 2.7.3 rom.

nonvolatile memory by Maki Kato — last modified 2005-02-04 09:44

I finally found it. The chip that's responsible for the nonvolatile memory. It's a CAT35C104P a 512 byte serial eeprom. Smaller than I expected, but now found nonetheless.

ncdtest3.s by Maki Kato — last modified 2005-03-31 00:45

a program to patch the isr and count the number of times it's called.
